Hi Kevin - I do not receive any notice or message - never have. That's the biggest issue. There's been no way to know that emails are not going through as they appear (as they always have) in my "Sent" folder. I only know that in the past few months two of my frequent contacts (Comcast users) now no longer receive my emails (based on their lack of response and my calling/texting them to repeatedly ask, "Did you get my email???" To which the answer is always, "No." Other contacts do receive my emails with no troubles. Then there are those emails recently sent - to which there are no replies (and no other way to contact the recipient) - - so I can only assume they were 1) received but ignored OR 2) never received like the Comcast accounts holders. Also - please see my other post related to this: forums.cox.com/.../sent-emails-successfully-reaching-bcc-parties-but-not-the-intended-to-recipient
